…tPropertyOfType` e350c35 (microsoft#40228) introduced a subtle bug: it switched the flags to an alias, dropping `SymbolFlags.Property` --- and that makes `symbolIsValue()` get to the `resolveAlias(symbol)` call, which leads to `getPropertyOfType()` with`resolved.callSignatures`+`constructSignatures` being `undefined`. So initialize them in `setStructuredTypeMembers` before calling `getNamedMembers()`. Fixes microsoft#42350
